The Calibre and Magnum deposits are part of the Citadel Project's large 1,330km2 tenure. Within the Citadel Project, the mineralised material is covered by desert sand and sediments to a depth ranging between just 10 to 100m. Calibre and Magnum currently constitute global Mineral Resources of 108Mt at 0.72 g/t gold, 0.15% copper and 0.54 g/t silver for 2.44Moz gold, 162kt copper and 1.8Moz silver with Calibre having a Mineral Resource of 92Mt at 0.72 g/t gold, 0.11% copper and 0.46 g/t silver for 2.1Moz gold, 104kt copper and 1.3Moz silver and Magnum having a Mineral Resource of 16.1Mt at 0.70 g/t gold, 0.37% copper and 1.00 g/t silver for 334,000oz gold, 58,000t copper and 0.5Moz silver. Both deposits are located approximately 45km east of Rio Tinto's Winu coppergoldsilver deposit, which Rio Tinto is continuing to explore and advance development studies on with first ore from Winu expected in 2025, subject to regulatory approvals, traditional owner, and other consents. On 28 July 2020, a maiden JORC 2012 Inferred Mineral Resource of 503Mt at 0.35% copper, 0.27 g/t gold and 2.15 g/t silver (containing 4.4Moz of gold, 1.8Mt of copper and 35Moz of silver) was announced for Winu.
